Abstract

PURPOSE:To peel and remove the skin of an onion, neatly and completely, by feeding the onion by the vacuum caused by the stream of compressed air, and blowing away the skin by the air flow. CONSTITUTION:Compressed air is introduced through the inlet port 17 into the inlet path 16, and begins the gyration movement by the contact with the spiral groove 12 provided at the outer circumferential wall of a cylinder 10. The air flow is bent further by passing through the spiral groove 9 between the spiral blades 11, and blasted through the slant path 18 and the ring-shaped nozzle 7 at high speed as a spirally gyrating conical flow. The onion (a) is sucked rapidly by the vacuum generated at the release end 3, rotated by the spiral groove 4 of the inner wall of the cylinder 10, and released under rotation from the release end 3 accurately to the center of the upper separation chamber 25.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an onion peeling device which suctions and supplies onions 2 using vacuum pressure generated by blowing out compressed air, and which blows and peels the onions. In a peeling device, it is necessary to uniformly generate vacuum pressure throughout the passage through which the onions flow, and it is also necessary that the onions move straight through the center of the peeling passage without wobbling. Otherwise, the onions will not be ejected in the correct direction to the center of the separation chamber provided opposite the discharge end of the passage, and will collide with the peripheral wall of the separation chamber, resulting in dents, damage, etc. . In addition, in order to blow off the skin of the onions by blowing the compressed air against the onions released from the discharge end of the passage, it is necessary to blow out the compressed air at a reasonably high speed, and the wind speed can be easily adjusted. It is convenient to make it possible.

Note that (90) in the figure is a cleaning device for cleaning the inside of the outer tube (20) provided at the curved portion of the skin outlet tube (68).

The present embodiment is constructed as described above, and its operation will be described next.

Onions (,) having a particle size that matches the inner diameter of the passageway (1) are continuously fed one by one from a conveyor device (40)K directly below the cylindrical body (10) at a predetermined interval.

A compressed air blowing device (
15), when compressed air enters the compressed air introduction path (16) from the introduction port (17), it first begins to spiral due to contact with the spiral groove (12) formed on the outer peripheral wall of the cylinder (10). , which is further bent as it passes through the spiral groove (9) between the spiral blades (11), and then passes through the inclined passageway (18) and exits from the circumferentially annular compressed air outlet (7) into a spiral swirl. It becomes an air current and blows out in a conical shape at high speed. Therefore, the inside of the conical swirling airflow, that is, the cylinder (10
) creating a vacuum pressure at the discharge end (3) of the passageway (1);
The vacuum pressure is created uniformly throughout the butterfly passage (1), and increases rapidly when the onion (, ) is located directly under the suction end (2) of the passage (1), so the iron onion (a) is Inhale rapidly into passageway (1).

While the onion (,) is sucked in and rapidly rises through the passage (1) ft, rotation is given by the spiral m (4) provided on the inner peripheral wall of the cylinder (10), and the iron onion (,) rises through the passage (1) ft. ) while rotating, and is emitted from its ejection end (5), and combined with the effect of the swirling airflow, it is ejected in the correct direction to the center of the upper separation chamber (25).

The swirling action of the compressed air and the rotating action of the onion (,) described above cause the onion (a) to move straight through the center of the passageway (1) without wobbling, and to be ejected neatly into the center of the separation chamber (25). However, it is just that these effects are more preferable, and it is up to the discretion whether or not these effects should be performed. However, at least the compressed air can be blown out evenly over the entire circumference from the peripheral wall of the passage (1), and the lines of blowing action of the compressed air can be blown out so that they intersect with each other on the center line of the passage (1). (1) Since a uniform vacuum pressure is generated throughout, the onion (a) can be moved straight through the center of the passage (1).

While the butterfly passes through the separation chamber (25), compressed air collides with it at high speed, so the skin part (C) of the iron onion (1) is blown away. The skin is neatly peeled off O The peeled onion, that is, the peeled onion (@ is the left rotating body of the direction changing device (60) rotating in opposite directions in the upper part of the separation chamber (25) 61) and the inclined angle of the right rotating body (61)' (66).

(66)', the horizontal component of the reaction force causes the ball to change direction laterally, and then passes through the outlet (26) to the peeled ball outlet pipe (27). On the other hand, the skin part (0) ti of the peeled ball (b), the drum-shaped rotating bodies (6) of the left rotating body (61) and the right rotating body (61)'
5).

(65)' and rises to the passageway (67)' formed between the skin outlet tube (68)? After passing through the separator (80) and collecting it, it is discharged to the outside.

In the above case, even if the peeled ball 0) collides with the inclined bar (66), (s6)', the ball <-(66)
.

The cushioning body (65) covering the (66)', (65)' does not cause scratches or damage to the peeled ball (b).Next, the compressed air outlet ( 1) The gap or opening degree is determined by an adjustment device (50) connected to the lower outer periphery of the cylinder (10).
adjusted by. That is, by rotating the handle (51) in the desired direction, the handle (51) is rotated in the desired direction.
) The worm wheel (54)'fr: rotates through the rotating shaft (52) of the worm (53)'(r), and this rotation causes the iron film to be applied to the lower outer periphery of the cylinder body (10) through the gear (56). The air is transmitted to the rack (57), and the cylinder (10) can be moved upward or downward via the rack (57). It can be adjusted either way.

By adjusting the opening, the speed of the compressed air blown out from the air outlet (7) can be varied. Due to the different adhesion strength of the skin,
It is possible to easily obtain the wind speed and air film according to these conditions, so it is possible to easily obtain the wind speed and air film according to these conditions.

According to the present invention, the compressed air is blown out evenly over the entire circumference from the peripheral wall of the passage, and the lines of blowing action of the compressed air are blown out so as to intersect with each other on the center line of the passage, so that a uniform vacuum is created throughout the passage. Due to the pressure generated, the onion can be driven straight through the center of the passage and thus discharged in the correct direction to the center of the separation chamber. Therefore, when the onions are discharged into the separation chamber, they do not collide with the peripheral wall of the separation chamber, and no dents or damage occur. In addition, since the opening degree of the compressed air outlet can be adjusted, the wind speed and air film can be adjusted to suit the onion particle size and production area, making it possible to accurately peel onions.
